QUILTING-FRAME FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 396,328, dated January15, 1889.

Application filed September 26, 1887- Serial No. 250,737. (No model.)

To all whom it 71mg concern..-

Be itknown that I, HENRY T. DAVIS, of the city, county, and State of NewYork, have invented certain a new and useful Improvement inSewing-\Iachine Quilting Attachments, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, and in which Figure I is aperspective view of the improvement, showing the same attached to asewing-machine. Figs. II and III are perspective views of the end barsof the frame. Fig. IV is a detail perspective view showing the oppositeends of the central cloth-roller. Figs. V and VI are views, partly insection, showing winding-rolls in different positions. Fig. VII is adetail perspective view showing the opposite ends of the winding-roller.Figs. VIII and IX are detail longitudinal sections showing the lockingends of the lining-roller in its different positions. Fig. X is a sideview of the inserted ferrule. Fig. XI is a detail longitudinal sectionof one end of a winding-roller. Fig. XII is a detail perspective viewshowing the rail-joint and inelin ed jointbar. Fig. XIII is a detailside view of the rail-joint with the sewing-machine table in verticalsection. Fig. XIV is a detail perspective view showing the tcnter-h ook.Fig. XV is a detail perspective view of a part of one of the strips ofcloth by which the quilt is connected to the winding-rollers. Fig. XVIis a perspective viewof one of the gudgeon-sockets, and Fig. XVII is asimilar view of another of the gudgeon-sockets of the winding-rollers.Fig. XVIII is a perspective view of the legbracket. Fig. XIX is a detailview of the top of one of the legs.

A part of a sewing-machine table is shown at 1, and the head of asewing-machine at 2.

The sewing-machine forms no part of my invention, although the inventionis to be used with a sewing-machine.

3 4 is a rail composed of two parts (3 and 4) in line with each other,and connected together by means of an inclined bearing-bar, 5, which isconstructed to rest on the top of the sewinganachine table 1. The part 3of the rail is secured to the bearing-bar by screws 6, or by othermeans, and by means of the clamping-bolt 7. The end of the part4 of therail is connected to the bearing-bar by a screw-bolt, 8, and by theclamping-bolt 7 at that end of the bar 5.

9 are clamps which engage beneath the edge of the table 1, and which arepressed against the same by the bolts 7, so as to hold the bar and rail3 4 firmly in position upon the table.

One or both ends of the rail 3 4 are provided with additional support bymeans of legs 10, which have at the upper ends screweyes or equivalentmeans of attachment to a bracket, 11, which is made fast to the rail.The means of connection I show between the rail and the legs consists ofslots in the bracket, through. which are passed the ring of thescrew-eye 12, and after this is done the screw-eye is turned one-fourtharound, so that the ring is transverse to the slot and so bears againstthe top of the bracket, while the upper end of the leg 10 bears againstthe bottom of the bracket. The bracket is so formed that the legs crosseach other, and their ends are so separated as to form a broad base ofsupport. (See Fig. I.)

13 is the central fixed rail of the frame, which is firmly fixed at itsends in the end bars, 14 and 15, of the frame.

The means of attachment which I show 0011- sists of mortise 16, cast ineach end bar and filled by a tenon at each end of the rail 13.

The end bar, 14, has three slots, 17, 18, and 19, open at the top andforming bearings for the gudgeons and 21 at the ends of the rollers 22,23, and 24, upon which the material is coiled. These gudgeons turnfreely in the bearings 17, 18, and 19, while at the other ends therollers carry means for locking them, so as to prevent their rotation,and thus the material between the rollers is kept sufficiently tight.The locking end of the roller 22 has a square or otherwise non-eirculargudgeon or pin, 25, which fits a notch, 26, of the same shape when thisend of the roller is in its normal (or lower) position, so that theroller cannot turn. The notch 26 has at top an enlargement, 27 in whichthe pin turns freely. Thus when this end of the roller is raised it canbe turned to unwind the cloth from it or to wind up the cloth upon it.

The roller is shown square in its body; but I do not confine myself tothis shape. It has a number of headed or plain pins, 28, to which isattached a strip of cloth, 2?),having buttonholes or eyes 30, to engageon the pins 28. This cloth is for the attachment of the edge of thequilt-lining 31, which is made fast to the opposite edge of the clothstrip to the eyes 30 by means of a row of stitches. After the lining hasbeen made fast to the strip 29 and the strip has been made fast to theroller, the lining is coiled upon the roller, leaving uncoiled onlyenough to reach the next roller, 23. Another piece of cloth, 29, is madefast to the opposite edge of the lining-sheet, and at the same time oneedge of the covering-cloth 32 is made fast to the latter strip 29. Thislatter strip should be wide enough (say eight inches) to reach theroller when the strip is made fast to the pins 28 upon the roller 24.The opposite edge of the cloth 32 is attached to another cloth strip,29, made to engage on the pins or buttons 28 of the central roller,lVhen placing the work upon the frame, the lining is coiled on theroller 22, as aforesaid, and the covering-cloth 32 is coiled upon theroller 23. The open edges of the lining and coveringcloth are now at thecentral roller, 23, and fast to the cloth strip 29, which is fast to theroller 24. The frame being put in position, if not in place already,with its bearing-wheel 33 resting in the groove 3% of the rail 3 4, aline, 35, of cotton bats is laid on the lining, and, by unlocking therollers and winding a part of the cloth strip 29 on the roller 24, theedges of the lining 31 and covering-cloth 32 are carried to the needleof the sewing-machine. The rollers are then locked in position, and onecorner of the quilt being brought beneath the needle, a row of stitchesis run across the quilt. Then the rollers are again unlocked, and thequilt being moved the distance for the next row of stitches, and theframe drawn back, another row of stitches is made after the rollers havebeen again locked in position.

The manner of locking the roller 22 in position has been alreadydescribed. I will now describe the device for locking the rollers 23 and24 in position, the means being similar in the two instances.

The gudgeon 35 of each of these rollers enters a bearing-socket, 36, inthe end bar, 15, said socket being surrounded by a circle of pin-holes,37, into any one of which may be made to enter a pin, 38, which isplaced a little distance from the gudgeon and parallel with it. Thisdevice is shown very clearly in Figs. II, IV, V, and VI. In Fig. II isshown the series of holes 37, in Fig. IV the pin 38, in Fig. V the pinis shown engaged in one of the holes, and in Fig. VI the pin is showndisengaged, so that the roller may be turned. The rollers 23 and 24: aremade so as to have sufiieient end-play to allow the engagement ordisengagement of the pin 38. p

In order to prevent the splitting of the ends of the rollers in whichthe gudgeons 20 and 21 are placed, I force into these ends of therollers ferrules 39, whose outer edges, 40, are preferably flanged over,so as to strengthen them at this part and to assist, by the entrance ofthe flange into the wood, in. holding the ferrules in place. (See Figs.VI, VII, IX, and X.)

The inclination of the inclined bearing-bar 5 is such as to increase theease with which the frame passes beneath the needle when making the rowof stitches. It will be seen that the part 4 of the bar may be removedfrom the part 3 and the block 5 by the loosening of only two bolts, andthen the parts may be folded together.

41 is a tenter-hook, which is supported 011 a rod, i2, extending fromone to the other of the gudgeons 21. The hooked end 42 engages in thematerial of the quilt, as seen in Fig. I, to prevent it being drawnendwise on the frame under the action of the feed mechanism.

It will be seen that the eye of the hook will slide freely on the rod 42as the quilt is rolled up on the roller 24:, and thus will present noimpediment to this operation.

I claim as my invention The combination, with the bearing-rail composedof sections 3 4, of the wedge-shaped bearing-bar, the bolt 8, passingthrough one section of said rail and the bar, the screws 6, passingthrough the bar and into the other section of rail, clamps 9, secured tothe ends of said bar, and the bolts 7, passing through the bar and railand said clamps, as set forth.
